A brake drum for a drum brake, in particular of a motor vehicle, includes a cylindrical jacket and a support pot which axially adjoins the jacket and which has a hub ring portion to be secured to a wheel hub. The monolithic brake drum is formed at least in part of a fiber-reinforced plastic.

In a carrier disk assembly for a brake assembly, and an electromagnetically actuable brake assembly with a carrier disk assembly, the carrier disk assembly has a hub part, two friction linings, and two disks. The disks are connected to the hub part, in particular with the aid of axially directed screws. Each one of the disks has a surface region provided with first depressions. A first friction lining is bonded and/or glued to the first disk in the surface region of the first of the two disks, and a second friction lining is bonded and/or glued to the second disk in the surface region of the second of the two disks.

The invention concerns a disc brake arrangement for a vehicle, the disc brake arrangement comprising: a brake disc that is rotatable about a rotational axis; and at least one brake pad, wherein the brake disc comprises a disc member and a brake lining at an outer circumferential face of the disc member and wherein the brake pad is displaceable relative to the brake lining, so as to contact the brake lining during braking for generating a brake force.

In some examples, a brake disc assembly including a single continuous core portion defining a core of the brake disc assembly; and a friction portion adjacent the core portion. The friction portion defines the friction surface of the brake disc assembly during a braking operation. The friction portion includes a carbon composite material. The core portion includes a core material that is not a carbon composite material, and the core portion is configured as a heat sink for the brake disc assembly for heat generated during the braking operation.

A brake disk may comprise a friction disk formed of at least one of a carbon fiber-ceramic matrix composite material or a carbon fiber-carbon matrix composite material. A first surface of the friction disk defines a first recess. A first ceramic insert comprising ceramic powder may be located in the first recess.

A braking arrangement includes a torque plate, a torque button, and a sacrificial bushing. The torque button comprises a head portion and a shaft portion, wherein the head portion is configured to extend at least partially into a torque pocket of an end plate of a brake stack and the shaft portion is configured to extend through an aperture disposed in a back leg of the torque plate. The bushing is configured to be removably coupled between the shaft portion of the torque button and the back leg of the torque plate.

A brake drum for a vehicle includes a friction ring and a drum body. The friction ring has grooves arranged on a radial outer surface along a circumference, and a coating formed on the grooves. The drum body is cast onto the radial outer surface of the friction ring so that the grooves are filled with a material of the drum body. The grooves include first grooves and second grooves. A first axial segment is formed at the friction ring in which the first grooves are introduced so that the first grooves are inclined relative to a first axial end of the friction ring. A second axial segment is formed at the friction ring in which the second grooves are introduced so that the second grooves are inclined in a direction which is opposite to that of the first axial segment. Each of the grooves have undercuts.

A friction part for a frictionally operating device includes a friction lining carrier and a friction lining. The friction lining includes friction lining pieces arranged in two rows to form an annular friction surface. The friction surface has an inner edge, an outer edge, and a groove set. The groove set has a first stem groove between the inner edge and a first branching point, a first branch groove between the first branching point and a first connecting point, a second branch groove between the first branching point and a second connecting point, a third branch groove between a second branching point and the second connecting point, and a second stem groove between the second connecting point and the outer edge. The first stem groove, and first and second branch grooves form a y shape. The second stem groove, and second and third branch grooves form an inverted y shape.

A friction part for a frictionally operating device includes a friction lining carrier and a friction lining. The friction lining includes pentagonal friction lining pieces arranged on the friction lining carrier to form an annular friction surface. Each of the pentagonal friction lining pieces has a two-dimensional shape made up of a rectangle and an isosceles triangle, and a base coinciding with a relatively long side of the rectangle. A radially inner row includes pentagonal friction lining pieces with a same first shape, a same first size, and a same first tip directed radially outward, and a radially outer row includes pentagonal friction lining pieces with a same second shape, a same second size, and a same second tip directed radially inward. The annular friction surface has an inner edge, an outer edge, and a groove set formed between the pentagonal friction lining pieces.

A brake disk may comprise a friction disk formed of at least one of a carbon fiber-ceramic matrix composite material or a carbon fiber-carbon matrix composite material. A first surface of the friction disk defines a first recess. A first ceramic insert comprising ceramic powder may be located in the first recess.
